Please help will give all my points and BRAINLIEST for this inequality’s worksheet. If correct will give double points after solving this worksheet.

Lance lived in portugal and brazil for a total of 14 months to learn portuguese. he learned an average of 130 new words per month when he lived in portugal, and an average of 150 new words per month when he lived in brazil. in total he learned 1920 new words. write a system of equations to represent the situation. use x to represent portugal, and y to represent brazil

Complete the solution of the equation. find the value of y when x equals to 28 x+3y=28

Which value of m will create a system of parallel lines with no solution? y = mx - 6 8x - 4y = 12
